Grid Pattern. The resistivity of silicon is too high to conduct away all the current generated, so a lower resistivity metal grid is placed on the surface to conduct away the current. The metal grid shades the cell from the incoming light so there is a compromise between light collection and resistance of the metal grid.

We have investigated the effect of front grid metallization design and geometry on the open-circuit voltage (V oc ), short circuit current density (J sc ), fill factor (FF) and efficiency (ŋ) of back surface field (BSF) silicon solar cells by using Griddler 2.5 simulation program.
Basic schematic of a silicon solar cell. The top layer is referred to as the emitter and the bulk material is referred to as the base. Bulk crystalline silicon dominates the current photovoltaic market, in part due to the prominence of silicon in the integrated circuit market.
Among electricity production sources for commercial and residential needs, silicon solar cells play a major role. Crystalline silicon is of crucial importance for commercial solar cells, since more than 90% of installed solar modules today are based on single- or polycrystalline silicon [ 1 ].
For silicon solar cells, the basic design constraints on surface reflection, carrier collection, recombination and parasitic resistances result in an optimum device of about 25% theoretical efficiency. A schematic of such an optimum device using a traditional geometry is shown below.
